I'll just point out something here... N8KOW mentioned mikebn's RS4's. If you want some of those they're through Ebay from Australia. Fantastic looking and best italian made quality BUT.... around £1300 including shipping without tyres. NO replica rim is worth that in my opinion. I'd go for a quality aftermarket for that price...Which is what i'll be doing.
Also, sorry to offend anyone but now that Audi fit RS4 style wheels to everything as an option they're a bit played out now and not as cool/exclusive.
Be careful with replicas though, there are loads you'll see on ebay for sub £500 with and without tyres...They're ***** quite frankly. Made in the far east from soft metal. If you've got a nice motor, give it the shoes it deserves i say.
Just my 10 cents!
